Get All StreamField Blocks of Specific Type
I have created a custom photoBlock to embed photos in a blog post. I am trying to create a template tag that would allow me to get every photoBlock that is stored in the database, almost like you query pages in Wagtail. I would prefer not to have to create a separate page for every photo, but instead be able to display them on a different page if possible via the template tag. class photoBlock(blocks.StructBlock): date = blocks.DateBlock("Date Image Was Taken") location = blocks.CharBlock(max_length=100) image = ImageChooserBlock() latitude = blocks.DecimalBlock(max_digits=9, decimal_places=6) longitude = blocks.DecimalBlock(max_digits=9, decimal_places=6) description = blocks.RichTextBlock() I am able to get the following to work, but it feels like the query is very heavy and will get bogged down once I have a bunch of posts. for page in BlogPage: for block in page.body.stream_data: if block['type'] == 'photoBlock': return block Is there any better way to query a specific block from Streamfield? Anytime I try something like this photoBlock.objects.all() I always get an error response that photoBlock doesn't have attribute Object. Any ideas? -
Prevent save_formset from saving - Django Admin
class VotesInline(admin.StackedInline): model = Votes class VoteAreaAdmin(admin.ModelAdmin): model = VoteArea inlines = [VotesInline, ] def save_formset(self, request, form, formset, change): if check_some_condition(): #prevent saving formset else: super(MyAdmin, self).save_formset(request, form, formset, change) All I want to achieve is - when a certain condition is met do not save the formset, do not make any changes in database. If I simply return when I try to finish, I get an error " 'VotesFormFormSet' object has no attribute 'new_objects' ". How can I prevent saving the formset? -

XML parsing with Django Rest Framework XML: elements of my request are missing
I use Django Rest Framework XML to create a simple api that accepts requests in XML format. The following view: from rest_framework_xml.parsers import XMLParser from rest_framework_xml.renderers import XMLRenderer class Process(APIView): parser_classes = (XMLParser,) renderer_classes = (XMLRenderer,) def post(self,request): print request.DATA combined with following request: curl -H "Content-Type: application/xml;charset=UTF-8" -H 'Accept: application/xml' -XPOST http://{server_address}:8000/process/ -d @books.xml works but the result of the xml parsing is not good (it seems to get only the last element of each node).

Make Django build contenteditable div for TextField instead of textarea
In my Django 1.10 project, I have a model: class Contact(models.Model): notes = models.TextField() ...and ModelForm: class ContactForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ContactForm, self).__init__(*args, **kwargs) for field_name, field in self.fields.items(): field.widget.attrs['class'] = 'form-control input-sm plain' if field.required == True: field.widget.attrs['required'] = '' class Meta: model = Contact fields = ('notes',) I have two questions regarding this: Can I make Django render the notes field as div with contenteditable=true rather than textarea? If yes, how do I automate the form.save() method? The second question is a bit vague, so I would be grateful for a hint regarding the first question. I have read through the doc, but couldn't find relevant section :( -
Django allauth, google login,using HD parameter
I am using django-allauth to login to my website using google login. I want to allow users having email from particular client, for that google provides the hd parameter. https://developers.google.com/identity/protocols/OpenIDConnect#hd-param SOCIALACCOUNT_PROVIDERS = { 'google': { 'SCOPE': ['email'], 'AUTH_PARAMS': { 'access_type': 'online' }, 'HD': '*****.com' } } I have used hd, using flask, and it worked pretty well, but I can't make it work here.

UnicodeEncodeError disparity between code run via django test suite vs django URL
Specifically I'm using the webob library where I posted a similar issue (https://github.com/Pylons/webob/issues/320), since I'm not sure if it's my usage, or a bug / documentation issue Take the following code: from webob.request import BaseRequest req = BaseRequest.blank('http://example.com/%D0%B4%D1%8D%D0%BB%D1%8C%D1%8D%D0%BD%D0%B9%D1%82') print req.environ['PATH_INFO'] print req.path If I run this via a django shell, I get: >>> req = BaseRequest.blank('http://example.com/%D0%B4%D1%8D%D0%BB%D1%8C%D1%8D%D0%BD%D0%B9%D1%82') >>> print req.environ['PATH_INFO'] /дэльэнйт >>> print req.path /%D0%B4%D1%8D%D0%BB%D1%8C%D1%8D%D0%BD%D0%B9%D1%82 Where as running it as part of a Django test case I get the following from the first print: /дÑлÑÑÐ½Ð¹Ñ Followed by the exception: File "/code/frontend/tests/test_views.py", line 55, in test_event print req.path File "/virtualenv/frontend/local/lib/python2.7/site-packages/webob/request.py", line 485, in path bpath = bytes_(self.path_info, self.url_encoding) File "/virtualenv/frontend/local/lib/python2.7/site-packages/webob/descriptors.py", line 68, in fget return req.encget(key, encattr=encattr) File "/virtualenv/frontend/local/lib/python2.7/site-packages/webob/request.py", line 175, in encget return val.decode(encoding) File "/virtualenv/frontend/lib/python2.7/encodings/utf_8.py", line 16, in decode return codecs.utf_8_decode(input, errors, True) UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-16: ordinal not in range(128) I get that this is probably some weird configuration with my test suite, however both run via the same method in the same environment (Django's manage.py test vs manage.py shell) and so I'm struggling to identify what's different. We're also running a ton of other unicode related tests without issue. Thanks for any light … -
Django - Logging into one subdomain of a website
Like Slack, you log into just one team, and not the entire system, how could this be achieved in Django? Using the django.contrib.auth module, we can log in the user to the website but I'm having difficulty understanding how to log a user into a subdomain. Apologies for the lack of code, but will I need to write my own custom log in? Thanks. -
django - dynamically generated form not posting data to request.POST
I've created a webform that consists of multiple forms and formsets on a single page. For the formsets, I made a button to add forms. When I create a new form using this button, the information I input into these forms is not POSTed and as such leads to an error in my formset as required fields are not filled out.

How to ensure lower server load in Django
I'm working on a Django web app. The app includes messages that will self-delete after a certain amount of time. I'm using timezone.now() as the sent time and the user inputs a timedelta to display the message until. I'm checking to see if the message should delete itself by checking if current time is after sent time plus the time delta. Will this place a heavy load on the server? How frequently will it automatically check? Is there a way that I can tell it to check once a minute (or otherwise set the frequency)? Thanks -

Building Cosign Filter for the Apache Webserver from Source docker
I need to implement and configure Cosign filter into Apache webserver. I'm running Apach in the docker container, so the problem I'm having is not knowing how to start implementing this, the documentation for this filter are good, but I'm doing this for the first time.

Django: How to use local copy of base theme?
I am working in Django 1.10, and have inherited a project. The base.html template extends a theme template that is not included in the project: {% extends "theme_base.html" %} It seems there is another theme repo, which is specified as a github URL in the requirements file. I now want to make changes to the base theme, but I'm not sure how to do this and run them locally. I have checked out a copy of the theme repo locally, and installed it with: pip install -U -e ../dc_base_theme But when I make changes in that local repo, they don't appear in my running Django site on localhost. How do I make sure my Django repo is pointing to that local copy of the theme? -
